DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 328,192, dated October 13, 1885,

Application tiled February 20, 18b5. Serial No. 156,536. (No model.)

To aZZ whom it may concern:

Be it known that I, Josnrn A. CoUL'rAUs, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Door-Holders, of which the following is a full, clear, and exact description.

This invention consists in a device of novel construction for holding room and other doors more or less open, and for preventing them from slamming when closing, substantially as hereinafter described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure'l represents a view in perspective of a door and door frame in part with my invention applied, and Fig. 2 a vertical section of the same,mainly on the linea: :vin Fig. 1.

A indicates the door; B, the door frame or casing, and C one of the hinges of the door.

Fastened on the back or opening side of the door is an upright socket plate or guard, D, constructed to receive freely and adjust-ably up or down within it the lower and straight tail end, b, of a spring roller-carrier, E, which where it projects above lthe guard D is of loop form or bent backward or outward and again forward and upward, as shown at c, and carries at its upper and forward end a rubbercoated or other roller, F. The lower or tail end portion, b, of said spring roller-carrier E is constructed at its bottom with a step-like projection, d, which, passing out through a slot, e, in the guard D, rests on an adjustingscrew, G, that works through a foot-piece on the guard, and which serves to admit of the spring roller-carrier E being raised or lowered for the double purpose of adjusting the roller F up or down and of varying the tension of the bent or elastic portion c of the roller-carrier when the roller is in contact with the surface against which it works.

Secured to and projecting from the upper rail or portion of the door-frame on the hinge side of the door, and corresponding to the circle or sweep of the roller F as the door is opened or closed, so as to form a bearing-sur- 50 face or track for said roller, is a plate or frame,

H, having any number of corrugations or curved pockets, f, one in rear of the other on or in the after part of the projecting portion of the plate or frame H for the roller F, pressed upward by the spring-carrier E, to enter and hold the door more 0r less open, according to the pocket f in which the roller is permitted to rest. The elastic construction ofthe rollercarrier E, however, the tension of which may be varied by adjusting the screw G, and the gradual curva-ture ofthe pocket portions of the frame H, admit of the doorbeing swung either way upon applying sufficient force for the purpose without any more positive lock of the roller in apocket, f, than is necessary to pre- 65 vent the door from being swung accidentally or by the wind. The invention accordingly provides for holding the door more or less open without restricting it from having its position changed or from opening or closing free from all manipulation of the device which holds the door more or less open. Thisis important, as it makes the door-holding device an automatic locking and unlocking one, and the same result may be accomplished in substantially the same manner by more or less changing the construction of the device. Thus, instead of the rollercarrier being bent to form aspring, the roller might be pressed upward by a spiral or other spring, which would also make the carrier a spring one, and other changes of details may be made without altering the characteristic fea'. ture of my invention.

The portion of the roller track or frame H in advance of the pockets f may be made plain or dat, as at g. to admit of the free and uninterrupted run of the roller during the early part of the opening and toward the end of the closing movement of the door, and said track or frame be formed with an `inclined shouldered projection, 7L, on the under side of its extreme advance end, which will serve, by forcing the roller downward against the pressure of its spring, to hold the door closed or from being too `freely opened, and likewise check the door 95 from slamming when being closed. To more effectually, however, prevent the door from slamming, a spring, I, may be attached to the door-casing or its attached frame H for the roller F to strike against as the door is shutto. IOO

This spring and the roller are shown in their respective positions by dotted lines in Fig. 2 as the roller commences to act npon the spring, and by full lines after the spring has been fully acted upon and the door closed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The roller track or frame H of the doorholder, having any numberof corrugations or pockets7 f, in the rear portion of its Workingsurface, and advance plain or flat portion g, and a forward projection, h, on or from the working-surface of the track, in combination with a roller device and a carrier therefor, with spring for forcing out the roller7 essentiall y as and for the purposes herein set forth.
